$\frac{ln 12}{3}$ $ln12/3$

In order to undo the $e$ $e$ power, take the natural logarithm of both sides of the equation.

Remember that the natural logarithm, $ln$ $ln$ , can also be written as " ${log}_{e}$ $log_e$ ".

We get: $3 x = ln 12$ $3x=ln12$

$x = \frac{ln 12}{3}$ $x=ln12/3$

How do you solve e3x=12 e^(3x)= 12?
